Solving Basic Linear Equations. An equation 129 is a statement indicating that two algebraic expressions are equal. A linear equation with one variable 130, \(x\), is an equation that can be written in the standard form \(ax + b = 0\) where \(a\) and \(b\) are real numbers and \(a ≠ 0\).For example \(3 x - 12 = 0\) A solution 131 to a linear equation is any value that can replace the ...
Linear Equations
A linear equation is an algebraic equation that contains variables that have an exponent that is not higher than one. A linear equation is called linear because when you plot the graph of the linear function, it will make a straight line graph. Examples of equations. 3 x − 5 = 7. 3 x-5=7 3x − 5 = 7. 2 x + 5 y = 1 5.

Solving Linear Equations
Solving Linear Equations. Solving linear equations means finding the value of the variable(s) given in the linear equations. A linear equation is a combination of an algebraic expression and an equal to (=) symbol. It has a degree of 1 or it can be called a first-degree equation. For example, x + y = 4 is a linear equation.

Linear Equations in Two Variables
By practising these questions students will develop problem-solving skills. Linear equations in two variables are linear polynomials with two unknowns. They are of the general form ax + by + c = 0, where x and y are the two variables, a and b are non-zero real numbers and c is a constant.
Solving Linear Equations
Worked-out examples on solving linear equations are given below. Instructions are given step-by-step with detailed explanation by using addition, subtraction, multiplication and division for solving linear equations. Examples on Solving Linear Equations: 1. Solve: (2x + 5)/(x + 4) = 1 Solution: (2x + 5)/(x + 4) = 1. ⇒ 2x + 5 = 1(x + 4)
Linear Equations
A linear equation is an equation for a straight line. These are all linear equations: y = 2x + 1 : 5x = 6 + 3y : y/2 = 3 − x: Let us look more closely at one example: Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x;
